No notice can be taken of anonymous communications. 
All quenes or answers should be accompanied by the name

[1.]—GALLIC ACID SOLUTION. — A. P. S. would 
Lave well rubbed the gallic acid in a mortar and made into a 
solution with 5vj of the S. V. R. and aq. rosae previously 
mix ed, and have rinsed out the mortar with the remaining 
5iv; he would also have affixed a “shake the bottle ” label 
above the ordinary label. He thinks it impossible, according to 
all writers and liis own experience, to keep gallic acid “ in such 
■a concentrated state ” in solution, except at about 200° F. 
I beg to say that I should have dispensed the prescription as 
follows:— 
Introduced the sp. vini rect., aqua rosse and acid, gallic, into 
a test-tube, shaken them together and applied heat until a 
perfect solution was obtained, after which I should have 
poured it into the bottle I intended for it. When I found 
that the mixture “ congealed ” on cooling, I should have as¬ 
certained what directions the prescriber had given for its use. 
It they were such as could be applied to the mixture in the 
congealed state, or when “ liquefied,” by placing the bottle into 
a vessel containing “ hot ” water, well and good; but, if other¬ 
wise,. I should have communicated with the prescriber, in¬ 
forming him that the mixture could not be used, if made up 
in the manner prescribed, and suggesting that a “ perfect ” so¬ 
lution might be obtained by subtituting “glycerine and otto 
of rose ” for the aq. rosrn, or “ acid, tannic. ” for the “ acid, 
gallic.,” either of which when treated in the above manner, 
will form a mixture that does not congeal on cooling.—

M. will find every information required as regards the mount¬ 
ing of objects, etc., for the microscope in Wood’s £ Common 
Objects for the Microscope,’ Is., or Lankester’s ‘ Half Hours 
with the Microscope, 3s., either of which he may procure 
from any London publisher. The latter is an excellent little 
work.—J. T. C.

spondent sends the following:—Magnes. sulph. c. potass,

Burns with great brilliancy; yields no smoke. —A. H. J. 
Answers have also been received from “ Cor sock” and J. F. 
Follard, giving recipes essentially the same as the above. 
UIL D’ARCHAL.—While looking for something else, 
the communication of “Ignoramus” in the Journal for 
July 30 has just caught my eye. The articles in question be- 
long, if I am not mistaken, to a small perfume lamp, of which 
I have a specimen. It is not unlike an ordinary spirit-lamp, 
except that the wick is confined in a glass tube fitting loosely 
m the neck, and retained in its place by a flange at its upper 
To use the lamp it is partly filled with perfumed spirit, and 
the stalk or “ handle ” of the platinum ball is thrust into the 
wick so as to allow the latter to project a little above the ends 
or the strand of cotton composing it. The wick is then ig¬ 
nited, and when the platinum sphere is red-hot the flame is 
blov n out with a sharp puff. It shielded from draughts of 
air, the metal ball will retain its temperature by continuing 
to decompose the vapour of the spirit rising through the 
wick.— J. F. Brown. 
( OIL OF HERMES.— T>. C. L. writes in answer to 
‘Queer ern” that syrup of red poppies is sold as oil of kermes 
in the West of England. 
[12.]—TEETH STOPPING.—“ Odontalgia ” would be 
glad ot a good formula for metallic cement for teeth-stopping.

dents tell me how to make an elegant preparation of the fol¬ 
lowing French recipe ?

[14.]—SACHET PERFUME.—“ Ignoramus ” wishes to 
know the best method of perfuming a writing-desk, or mak¬ 
ing a suitable sachet for the same object. 
[15.]—MEZEREON EXTRACT.—Is the mezereon ex¬ 
tract contained in the lin. sinapis comp, of any other use than 
as a colouring agent ? 
[16.]—ROME AND PARIS.— A. S. asks at what hour the 
pharmaciens in Rome and Paris close in the evening ? 
[17.]—AQ. MENTH. PIP.— W. S. R. wishes to be in¬ 
formed why aq. month, pip., made with the foreign oil, turns 
pink upon exposure to the light. 
[18.]—RUBINI’S CAMPHOR.— J. Botham wishes for a 
formula for Dr. Rubini’s Camphor. 
[19.]—SALE OF POISONS.— F. P. W. wishes to know 
if grocers can legally sell “ Wheat Dressing ” and “ Fly 
Powder for Sheep,” or whether these preparations are to be 
classed as vermin killers. 
[20.]— BLEACHING LARD.— T. B. Alikins wishes to be 
informed of a cheap and easy method of bleaching lard, with¬ 
out impanlng its qualities for domestic use. 
[21.]—GLYCERINE JELLY.— B. W. W. (Sheffield) is 
in want of a good recipe for making glycerine jelly. 
[22.] — COSMETIQUE. —A. P.S. would be glad of a good 
recipe for making brown cosmetique for fixing the hair and 
moustache. 
[23.]—COLOURING FOR POMADE.— S. W. S. (Hull) 
would feel obliged by any of our readers telling him of a good 
colouring ingredient for pomade (yellow) which will not fade 
with the light.
